MOS was pretty okay. Action-wise, very solid. I like Henry Cavill, so I didn't dislike his Supes rendition. Also, Antje Traue made me hardwas awesome.
The storytelling was kinda meh for the first 20 minutes or so though. Even as a non-Supes noob, I was thinking "Wtf is going on and where are we going?"
There's far worse out there though. Like Daredevil, Elecktra, Batman and Robin, Superman III, etc.
